AFM and MAF???????????

[Conan]

Could some explain the difference?

what are the differences?

why is one more restrictive than the other

are MAF a good idea on something smaller than a 2.7 etc

CHEERS

AFM uses a flap system where it measure the volume of air.

MAf uses hot wire/hot mesh to calculate the MASS of air and works much fatser than an AFm and measures more accurately. Its also non restricitive and is basicaly near anough a hollow tube.

Gains seen before on a 2.5 are a minimum of 10bhp and 10 lb.ft torque peak and more throughout the rev range.

Well worth it especially combined with a 6 branch and BBTB.

cheers, looking to buy a 2.7 of a mate and wondered the gains on that if i changed to MAF?

[Turbo-Brown]

I'd look at the cost of the MAF compared to a mappable ECU setup as there might not be much in it, in which case you may well stand to gain more from the latter

and give more choice later on should you choose to take it futher..

so.....what is the procedures and parts do it need to change my 325i into using air mass sensor unit?

thanks in advance?
